memcg: make the v1 soft limit knob inert

2026-09-02T03:26:20+00:00

The v1 soft limit has been deprecated since v6.12 and nobody has reported depending on it. Start the removal by decoupling the interface from the implementation: keep memory.soft_limit_in_bytes, but ignore writes to it and always report the maximum value on read similar to what memory.kmem.limit_in_bytes already does. Writes are still parsed, so malformed input keeps returning -EINVAL. The knob now also behaves the same everywhere: it used to return -EOPNOTSUPP on PREEMPT_RT, where soft limit reclaim has always been disabled. This also fixes the syzbot report linked below. Soft limit reclaim is the only caller that runs shrink_lruvec() from kswapd against a specific memcg, so it is the only way to reach lru_gen_shrink_lruvec() and in turn set_mm_walk(), which warns when called from kswapd.

netlink: specs: add missing mask attributes for conntrack dump

2026-08-28T22:34:51+00:00

'mark-mask' and 'status-mask' are defined and supported by the conntrack dump, but missing from the list of arguments. While at it, the order of the arguments should follow the order of their definition in the enum ctattr_type. That appears to be a common convention for other spec files.

netlink: specs: fix the conntrack filter type

2026-08-28T22:34:51+00:00

The CTA_FILTER doesn't contain nested tuple attributes, instead it contains bit masks that specify which tuple attributes to filter on. The values for filtering are taken from the top-level CTA_TUPLE_ORIG and CTA_TUPLE_REPLY, which are also missing in the attribute list for the dump request. The bits themselves somehow are not in the public headers, so not defining them in the spec either for now. Once they are public in uAPI, they can be added here with enum-as-flags.
